The SizeType enumeration specifies how rows or columns of UI elements, typically controls, should be sized relative to the size of their container. This enumeration is used by the RowStyle and ColumnStyle classes to indicate their preferred sizing attributes. The TableLayoutPanel class, in turn, uses these style classes.

When laying out a container with rows or columns that have different preferred sizing attributes, any space remaining after the initial allocation will be distributed between the rows or columns whose styles have TableLayoutStyle.SizeType property values of AutoSize or Percent.
